RlVET-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 394,722, dated December 18, 1888.

Application filed May 24,,1888- Serial No. 274,995. (No model.)

To aZZ whom it may concern.-

Be it known that I, CLARK M. PLATT, of

.Waterbury, in the county of New Haven and State of Connecticut, have. invented a certain new and useful Improvement in Rivet-Setting Machines, of which I declare the following to be a full, clear, and exact description, reference being had to the accompanying draw- Figure 1 is a side elevation of my rivet-setting machine; Fig. 2, an under side view of feed-ratchet and plate; Fig. 3, a perspective view showing curvature of chute; Fig. 4, a top view of lower end of chute and section, showing details of receiver; Fig. 5, a cross-section in line 0000, Fig. 3; Fig. 6, a cross-section in line y g, Fig. 3; Fig. 7, a plan or top view of receiver; Fig. 8, an edge view of same.

Similar letters of reference indicate like parts in the several figures.

This invention relates particularly to that class of rivet and eyelet setting machines that are provided with a reservoir in which the rivets or eyelets are placed in bulk and from which they descend by an inclined chute to a receiver, from which receiver they are driven into a garment by the action of a plunger. Rivet and eyelet setting machines having this general construction are old, and need not, therefore, be particularly described, excepting so far as may be necessary to fully explain the construction and operation of my improvement on such machines, and such improvement primarily consists in so constructing the receiver of the machine as to particularly adapt it to be used in connection with a chute, A, whose lower part is formed with a twist or turn, B. This twist or turn is such that the surface of the chute is reversed from one end of the twist to the other, that which would have remained the upper surface of the chute by reason of the twist becoming the lower surface at its termination, as is shown in Fig.

T form in cross-section. (See Fig. 5.) In that part of the chute which extends from the reservoir C to the beginning of the twist B this channel a uniformly preserves its shape of section, as in Fig. 5, with its cross part I) downward and its stem 0 upward; but as this channel follows the twist B the parts I) and of the channel gradually reverse their position until at the end d of the chute the cross partb of the channel is uppermost and the stem 0 lowermost, as is seen in Fig. 6. Advantage is taken of this change in the channel, for, as will be seen by referring to Fig. 3, when a rivet, eyelet, or tack, e, is passed from the reservoir C with its head downward in the channel a and its point protruding upward through the same, it will gravitate downward in the channel, preserving that position until it meets the twist B of the chute, when the channel, still acting as a guide, leads the rivet from its straight course around the half twist or turn of the chute, as described, until the end of the chute and channel is reached, when it will be found that the rivet has reversed its position of point up and head down to that of head up and point down, which is the position desired for inserting the rivet in the garment or fastening a button to the garment, for which-purpose these rivets are generally used. The rivet, now in its proper position, having arrived at the end of the chute A, is carried by gravity into the receiverl), into which it passes point down and head up, and so remains until by the downward action of the plunger E the rivet is forced through the receiver, through the garment, and into the button, resting upon the anvil F, the end of the rivet being upset in the button in the ordinary manner. This receiver I), which operates in connection with the rivet e, is constructed with two jaws, f, pivoted at their rear ends by a common pivot, g, recessed as at h, and terminating at their front in flaring and cup-shaped ends 7c. Uniting the rear of these jaws is a spring, Z, which by its retroactive force permits the jaws to open and deliver the rivet when forced by the plunger, as stated, and afterward restores them to their closed position. Fixed to the sides of the jaws f are connecting-bars m.

3. In the chute is cut a channel-way, a, of i These bars extend to and are in contact with pivoted to the supporting-bar G, and they are constructed to close an opening, 0, in that bar, practically forming the bottom of a cylindrical recess made by the flaring ends 70 of the jaws f, the opening 0 in the bar G, and conical recesses r in these holders n, which reqess permits the introduction of the rivets head and stem into the receiver. The holders are united by a spring, 3, which impinges against the,

sides of the holders, as shown in Figs. 7 and 8, and its elastic force permits the opening and closing of the holders when the plunger E of the machine drives through the receiver the rivet contained therein, as before described. The rivet having passed through, the act-ion of the spring again closes theholders ends ready for the next rivet, and so on. These holders n are preferably made with wings p, with which the holders may be operated by the fingers when it is desired to remove a rivetwithout employing the plunger for that purpose. To the under side of the bar G is fitted a spring, H, with a pivoted ring, 2, which acts as a clamp for holding the fabric in place during the operation of riveting the button thereon; but as this clamping-device has already been patented to me in a previous patent I need not describe it any further.

The foregoing description of the twisted chute, combined with the rivet-receiver, substantially describes my improvement in rivetsetting machines, and the operation of the machine with these improvements is as follows:

The rivets are placed in bulk within the reservoir C. The heads of these rivets being the heaviest, they gravitate in the receiver head downward; but, as it is necessary that they should ultimately present their points downward in order to thrust the rivet through the garment on which it is to be employed,

some provision must be made for accomplishing this change in the position'of the rivet, and numerous devices have been employed to effect that change. Inmy present improvement, as the rivets leave the receiver head downward and so' follow the course of the channel (L, they are compelled to follow that channel throughout its half turn or twisted part B, and in so doing when they arrive at the end (Z of the chute they will have reversed their position, presenting themselves to the receiver D or the cup-shaped ends it of the jaws f of the receiver, within which the head of each rivet is received, the stem of the rivet passing downward through the hole 0 in the bar G and into the conical recess 1 of the holders n, and there it remains till the garment, with a button to be attached to it, is brought beneath the'rivet and in the desired position by the action of the anvil F, when the downward movement of the plunger E drives the rivet through the receiver and into the garment, as before stated, its point or lesser end being upset or clinched.

In my rivet-setting machine thewell-known cut-01f J is employed to deliver one rivet at a time to the action of the plunger.

' In order to effect the simultaneous opening and closing of the jaws f and the holders n, the bars m are employed to produce that result, when the holders n are operated by the ings 9, as stated, and also to some extent by the action of the plunger, the bars being fixed at one end to the jaws f, and their other ends in close contact with the sides of the holders n, and operating as levers when the holders 'n are pressed outward to force open the jaws f.

v Having now described my invention, WhatI claim as new, and desire to secure by Letters Patent, 'is

1. In the receiver of arivet-setting machine, the combination of the pivoted holders 01, connected by the spring .9, and the jaws f, pivoted at g and connected by the spring 6, said holders and jaws being secured to the arm G and so arranged that the opening between the ends 7a of said jaws registers with the conical recess '4', formed in the holders, substantially as and for the purpose described.

2. In a rivet-setting machine, the combina tion of the followingelements: the arm G, provided near its outer end with the hole 0, the

pivoted holders n, having the recess 0'' formed therein and connected by the spring 8, and the pivoted jaws f, provided with the arms on and the flaring ends it" and connected by the spring 6, said holders and jaws being se-' cured to said arm G and so arranged that the loo CLARK M. PLATT.
